Is there another location where I can get the nfs4 patches? That FTP seems
to be down.
Also, outside the scope of this list, but since the discussion is opened, I
might as well ask:
If this NFS is the only remote mount that involves writing (it's opened
read-only in other locations), and it's read/write locally, is it safe to
use local locking?
